Sensei's Divining Top + Starnheim Courser + Madame Web, Clairvoyant

Sensei's Divining Top

Starnheim Courser

Madame Web, Clairvoyant

How it works

1. Activate Sensei's Divining Top by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Cast Sensei's Divining Top from the top of your library by paying 0.
3. Repeat

By combining Madame Web, Clairvoyant's static permission to cast noncreature spells from the top of your library with Starnheim Courser's cost-reducing presence, we create a zero-mana loop with Sensei's Divining Top. You simply tap Sensei's Divining Top to draw a card and place it back on top of your library, where Madame Web, Clairvoyant lets you cast it immediately. Thanks to Starnheim Courser discounting artifact spells by {1}, that recast costs {0}, allowing you to repeat this cycle endlessly for infinite draws, draw triggers, and storm count.
